TURPENTINE-CCLLECTING orrf Specification of Letters Patent.

Patented Aprfis', 1911.

The object of my Vinvention to provide animproved construction of turpentine col-V lecting cup from which the gum may be readily removed, which may be securely` held in position `by a nail driven into the tree connection with the collecting apron, which may be easily-removed 'and replaced, and'v which will be capable of being rapidly and chea ly manufactured, and at the same time be e cient and durable.

To practically 'accomplish this result, and herein Vmy invention consists, I make the body of my cup of a trough vshape or Ul shapein cross section'and close the'ends of 4the trough by U shaped head lplates which' are double searned ,to the body, the cup being made of; plain -sheet steel and galvanized yafter .the heads are Vsecured to the'body, the galvanizing thus effect-nelly closing and making liquid tightv the seams 'which unite the body and head The trough shaped cup thus has a rounded bottom free from corners which adaptsth'e gumto befreadily ren ioved therefrom;v The rounded bottom of the cup also'adapts the cup to be very securely locked in'position by a wedging or lcannaction against the supporting nail 'or nails below, in connection with the collecting apron above.l The rounded bottom of the cup has a tangential contact -only'wlth the supporting nail or nails and Athuis cooperates with Athecollecting'apron under'whi'ch the upper," inner, longitudinal edge' of the Y trough shaped cup tits, and which is engaged, A

therebyas the roundingl bottom of thecupis forced inward toward the tree thuscausing Ithe cup to be'wedged betweenthe lsupporting nail below and the collecting a ronA above'.

' 'y wind or animals'.- v l `My invention alsoconsists 1n the lnovel constructions of parts, and devices and in the novel combinations of arts andV devicesjand more particularly specified in theV claim.

The cup is thus held firmly an lace so that it is not liable to -be dislo ged same 1n position on the tree. F ig. 2 is 'a lplace thereby in a horizontally transverse vand downwardly inclined position.

In the accompanying drawing forming a part ot this specification, Flgure 1 is a front elevation of a turpentine collecting cup and apron .embodying my invention, showing the vertical section on line 2 -2 of Figi 1. Fig. 3 is an enlarged top or plan view of the cup. Fig. ll is a longitudinal section on line 4 4 of Flg. 3. Fig. 5 is .an end View. Fig. 6 is a detail, partial, horizontal section on line G of Fig. 5. Fi 7 is .an-enlarged detail section' of one of t e double seams uniting the body to the head plate.

ln the drawing, 1 represents' a pine or turpentinebear'ing tree, 2 is the wide collecting apron, consisting'o a:l iece of galvanizec sheet steel, preferably' yaving a confcavely curved inner edge' 3 adapted to enter the gash l of .a tree, and to be held securely in .The apron has upturned, inclinedtlanges 5 at itsV end edges and preferably a depending lip 6 at its outer, horizontal,.longltudinal edge.

Myimproved cup comprises a longtrough shaped body 7 with a rounded bottom por-4 tion 8 and its sides 9 preferably slightly Haring. The upper,l longitudinal edges of the' body are preferably provided with 4foldgive the cup smooth edges. The body of the cup is thus U shaped in cross'section, i

`The ends of the trough shaped 'body are closed -by U sha ed head plates 11, 12 which on the head plates, which are interfolded with seam llang'esflfl on theends'lof 4the strengthen and sti en .the cup. The cup is 100 rigidly and 'firmly lsupported in. position:

The rounding bottom of the cup tlius adapts it to couct as a cam or wedge with the support-ing nail or nails in lconnection with the collecting apron which engages the inner upper longitudinal edge of the trough shaped cup.

The combination with a. tnrpentine collect- 15 ing apron and a cup support below the apron, of u removable, long, narrow trough shaped tnrpentine collecting cup having a round bottom rin cross section, the upper, horizontal inner edge of the cup fitting under and engaging the apron, and thel round bottoni of t-lie anp tnngentially engaging with a wedging or cam-like action the cup supportto lock the cup rigidly in position when the lower portion of the cup is forced inward toward the tree., snbetantially as specified.
